1. Direct and endothelium-linked serotonergic control of vascular tone in human uterine and umbilical arteries
Sammanfattning : The serotonergic vascular control was investigated by in vitro pharmacology in the human uterine and umbilical arteries. The localisation of immunoreactive (IR) neuropeptide Y (NPY) and the influence of NPY on the adrenergic vascular effects in the human uterine artery were also studied. LÄS MER
Sammanfattning : In this present study the population of endothelin-like receptors in the human umbilical artery was examined in vitro in different parts of the umbilical cord. Immunohistochemistry revealed ETB receptors in the endothelium and an uneven distribution of ETA receptors in the smooth muscle of the arterial wall, when comparing different parts of the umbilical artery.

Sammanfattning : The aim of this thesis was to develop an objective method for evaluation of umbilical artery circulation based on auditory perception of the Doppler sound signals. Study I. The operator listened to synthetically produced sound signals from continuous flow. LÄS MER
Sammanfattning : The aim of this thesis was to study maternal and infant effects of delayed cord clamping (≥180 seconds, DCC) compared to early (≤10 seconds, ECC) in a randomised controlled trial. Practice and guidelines regarding when to clamp the cord vary globally, and different meta-analyses have shown contradictory conclusions on benefits and disadvantages of DCC and ECC. LÄS MER
